Not exactly sure about the largest bit this tool will accept (maybe about 3/4").You will probably need to check on a much larger tool.

I am impressed by this unit's ease of use for householder applications. 4" probably exceeds design limits but with very patient, steady guidance, you will likely accomplish your task. Attaching Bosch T3923SC Extension Bar with Bosch 4 3/8" or 3 7/8" Speedcore Bits you may be successful. SDS Max offers higher level of success.Good Luck !

1-1/8 is the largest that is recommended. I have not had much luck with this tool, it's not up to usual Bosch standards

If it was were me, I would try it. The drill has plenty of power, just go slow and easy, and I think you will be okay.

I refer you to the Mini Micro Drill Bit Set and Pin Vise Chuck Product Description. The largest is (2 each)2.0mm 0.079" and yes there are (4 each) 1.0MM 0.039. Every drill bit is listed in the Product Description. 30 drill bits are included plus the Pin Vise Chuck for total of 31 pieces. My set was very well made and in my opinion was built to cost much more. JLH

I don't have the bits at home, but I'm almost certain it's OD. I bored through an 8" thick block wall that was grouted, all I had to do was remove the core as it built up and I could drill deeper than the bit. I think the bit is 6" deep. Also, make sure you keep plenty of water running over the bit as you bore. I rigged a small siphon hose to keep the hole wet. Hope this helps.

I used mine to install an above ground hoist on 4 inch steel reinforced concrete floor. It drilled 10 5/8 inch holes with out a problem. I am not sure how much larger bit a 1/2 inch drill will hold but con considerably more.

No, it is a impact for screwing long screws or bolts. The chuck only excepts a 1/4" hex shank. I don't believe they make a 1/4" hex concrete bit.

I think that a 1/4" bit will fit into the chuck, but the motor doesn't have the torque to push it through anything harder than wax. This machine is a sweet running little drill press, but it is seriously lacking torque. It is only for drilling very small holes in light or thin material. It took me several minutes to drill a 1/8" hole in 1/4" aluminum. Good machine for what it's made for.

It's got lots of power and sturdiness so I think it'll do fine with the correct bit. You might go through a few bits, depending on depth and strength of concrete but the drill will hold up.

These bits are for concrete drilling. You will need a drill that will be able to take a 1/2" shank for larger bits . If you're drilling many holes go with heavy duty electric hammer drill. If you're a homeowner go with heavy duty hammer drill 18 volt or above. Hammer drills take a beating don't waste your money on cheaper models. Go with any heavy duty model bosch hammer drill either electric or 18 volt cordless and you will be able to use these bits.

Hello Cheryl, Thank you for asking about our Dewalt drills. For concrete and masonry, we believe any of the Dewalt hammer drills would be able to use a 1/2" bit. The strength of the drill would be determined by the specifications of your project. You can read about the various drills here: www.dewalt.com You may want to also contact DeWalt directly about this matter to get a more precise answer. Have a great day!

The bits are about six inches. They will go through a 2x4 and a 4x4 with little problem, but if you need longer, you will need an extension bit. Harry

Yes... if you can find Concrete Bits that fit the quarter inch Hex, go for it... I love my impact... really good for driving screws and bolts in to masonry or Concrete... Never used Concrete bits in impact...Yet... but you can buy bit and screws in a kit... just drill the hole like normal... unless your planning to use the huge ones... but in Cynder blocks... works fine. I also drilled 3/8 inch lags screws, into predrilled holes... do not drill holes bigger then the shaft of the screw.. if you drill them the size of the threads... will not gripI hope this helped...

I think 1/8 " drill bit is big enough. Important is to spray paint the part to the wall AND the shower curtain rod with rustoleum. In about 1 yr the humidity will build up AND you will see drops.

I used a 1/8 inch bit. Maxxair website should list that, plus it is listed in instructions. Very easy.

I glanced at the product description for that p20 drill and it says it holds 1/4 hex bits. This clic change piece is 3/8" or larger.
